Personally, I think most of it is pseudoscience due to irreplicable nature of the study.

But even if it were true, why should what is natural be considered "right?" It seems that everyone who claims something is human nature does so to justify that action, which seems a bit ridiculous. I mean, you could argue it's human nature to separate into tribal groups and relentlessly wage war against outsiders whose views and lifestyle conflict with your own...but is it right?

What are your perspectives towards evolutionary psychology and what would they be even if evolutionary psychology had merit?
